Processor and Chipset Intel® Server Board SDS2

3.Processor and Chipset

The Server Works* ServerSet III HE-SL chipset provides the 36-bit address, 72-bit data (64-bit data + 8-bit ECC) processor host bus interface, operating at 133 MHz in the AGTL signaling environment. The HE-SL North Bridge provides an integrated memory controller, the interface to 32-bit, 33-MHz Rev 2.2 compliant PCI bus, and two Inter-Module Bus interfaces. The Inter- Module Bus (IMB) provides the interface to two 64-bit, 66-MHz Rev 2.2 compliant PCI buses via the CIOB20.

The SDS2 DP Server Board directly supports up to 6 GB of ECC memory, using six PC-133- compliant registered SDRAM DIMMs. The ECC implementation in the HE-SL can detect and correct single-bit errors, and it can detect multiple-bit errors.

3.1Processors

The SDS2 Server Board supports two Intel® Pentium® III processors in the Socket 370 FCPGA2 package. If two processors are installed, both processors must be of identical revisions with the same core voltage and speed for the bus and core. If one processor is installed, an AGTL terminator module must be installed in the other socket. The support circuitry on the Server Board consists of the following:

∙Dual Socket 370 FCPGA2 processor sockets supporting 133-MHz FSB (if using one processor, an AGTL terminator module goes in the empty socket)

∙Processor host bus AGTL support circuitry, including termination power supply
